Window Wall Major Cost Factors
Window walls are made of custom, floor-to-ceiling windows, so the cost range is big—between $700 and $1,600. Below are the major price factors.
- Glass type: Some types of glass are more energy-efficient and durable, which increases the price.
- Labor: Professional glaziers typically charge per hour. Labor costs vary by location.
- Permits: Your window wall project may need a permit depending on your wall size, type, and location.
- Structural engineer: You may need to hire a structural engineer to ensure your window wall is stable and safe. This can add thousands of dollars to the total cost but is well worth the investment.
Homeowners can choose from various types of glass. This can significantly change your project price. Here are some examples of window wall glass types.
- Single-pane glass ($50 to $100 per window): This is the most basic and affordable type of glass for a window wall, but it’s not very energy efficient.
- Double-pane glass ($100 to $300 per window): Double-pane windows have better insulation due to the gas layer trapped between the panes.
- Triple-pane glass ($300 to $1,000 per window): Triple-pane windows have three panes of glass with an extra layer of insulating gas.
- Low-e glass ($300 to $1,000 per window): Low-emissivity (low-e) windows have a special coating to help improve energy efficiency, thus reducing your energy bills. According to the United States Department of Energy (DOE), windows with a low-e coating can reduce energy loss by 30% to 50%.
- Laminated glass ($10 to $20 per square foot): Laminate is another type of safety glass made of two or more glass panes joined by a plastic film layer. This type of glass comes with additional features, such as moisture protection.
- Tempered glass ($12 to $13 per square foot): Also known as safety glass, tempered glass is the most durable type of glass and can withstand extreme weather conditions.
Cost by Glass Type
|Glass Type||Average Price|
$10–$20 per square foot
$12–$14 per square foot
You’ll need to hire a licensed and insured glazier. A glazier specializes in installing and working with different types of glass. Glaziers charge $35 to $150 per hour depending on your location, the project’s scope, and the glazier’s experience level.
You may need a building permit depending on your window wall project, location, and local rules. Removing brick or drywall often requires a permit. It will cost $150 to $2,000 depending on your municipality. Ask your glazier about permits before your project begins.
If your walls need extra structural support, you may need to hire a structural engineer to ensure your glass walls are stable and safe. Most structural engineers charge per project at a rate of $300 to $5,000. A large project may require an inspection, which adds another $500.
Professional vs. DIY Window Walls
Window wall installation is an advanced project and should only be done by a professional glazier. A glass wall provides structural support to your home. A small mistake could put cracks in the wall or compromise the glass and the home’s structural integrity. This could lead to a dangerous situation for you and your family.
If the wall doesn’t support the home’s weight, a pro will need to frame it to ensure a tight fit. Any spaces between the frame and wall could result in higher energy bills. A glazier will also make sure the track doesn’t warp and prevent the glass door or sliding doors from opening or closing. Only a structural engineer and a glazier are capable of completing this job safely and correctly while following local building codes.
Professional Window Wall Installation
Hiring a professional window wall installer will save you time and money while ensuring your and your family’s safety. They’ll also be able to manage all project aspects, such as selecting materials and acquiring building permits. Some glaziers offer installation warranties to guarantee their work.
Before beginning the project, you’ll meet with the glazier to discuss your needs, look over home blueprints, and determine if you need to hire a structural engineer. You’ll also review the project timeline. The glazier will then order all necessary materials, get the required permits, and remove any existing glass.
Next, the glazier will measure and prepare the opening and install the frame and glass panels. After, they’ll check that it’s properly fitted and the windows open, close, and lock smoothly. Once the window wall is sealed and weatherproofed, they’ll test for any potential leaks and drafts. Once the glazier finishes the interior and exterior surfaces around the window wall, the job is complete.
How to Reduce Window Wall Costs
Window wall installation is expensive, but it’s well worth the investment. Still, there are a few steps you can take to help reduce your window installation cost.
- Compare multiple quotes: Reach out to several glaziers, and request project quotes. This doesn’t mean you should select the cheapest option, but it will give you a better idea of fair prices.
- Choose thinner glass: Thin glass walls cost less, but you should ask a professional what types of glass you can use based on your project.
- Invest in energy-efficient upgrades: Choosing energy-efficient upgrades can help save you money on energy bills. According to the DOE, of the $2,000 the average homeowner spends on energy annually, $200 to $400 is wasted due to drafts, air leaks, and outdated systems.
- Install a window wall during the offseason: Most homeowners opt for window replacements or installations during spring and fall. Glaziers may offer better prices during slower times of the year.
- Purchase materials in bulk: You may think it’s more cost-effective to spread this project out over time, but window companies typically offer better deals when windows are purchased in bulk.
- Request warranties: Purchase materials that are backed by warranties, and hire a professional glazier who offers some kind of guarantee on their work.
- Purchase ENERGY STAR-certified windows: Thanks to the 2022 Inflation Reduction Act, a federal tax credit is available to homeowners who install ENERGY STAR-certified windows. ENERGY STAR says that homeowners can claim up to 30% of installation costs for a maximum credit of $600.
- Check for rebates or incentives: Your local utility company may offer deals on professionally installed ENERGY STAR or energy-efficient windows. Some states also offer tax credits and rebates on energy-efficient home improvements.
- Choose an alternative type of window: Choosing a different type of window, such as a bay window, is a great alternative to achieve a window wall’s look. Bay windows are available in a variety of configurations.
How to Hire a Professional
Here are some tips for hiring a pro for your window wall remodel.
- Check reviews for local glaziers and ask friends and family for their recommendations.
- Read customer reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Trust Pilot.
- Contact multiple pros and ask about their experience, availability, and rates.
- Check whether the glazier has the proper licensing and insurance in your state.
- Ask your chosen installer for a project timeline.
- Get cost estimates, guarantees, or warranties in writing.
Whether you’re looking for more natural light or improved views of the outdoors, window walls can give your home the perfect high-end look. However, a window wall is expensive, especially if you opt for energy-efficient windows. Adding extra structural support can add thousands of dollars to the final price tag.
The results of this project are stunning, but don’t attempt to do the installation yourself. We recommend getting multiple quotes from the best window companies in your area.
FAQ About Window Walls
Are window walls more expensive than regular walls?
Yes, window walls are more expensive than regular walls due to the cost of glass. However, window walls offer several advantages, such as natural light, which make them worth the investment.
What is the difference between a window wall and a curtain wall?
Window walls are built one floor at a time and are supported by slabs above and below, while curtain walls are structurally independent. Curtain walls aren’t load-bearing, which means they can’t replace a load-bearing wall.
How thick should the glass in a window wall be?
The best glass depends on your specific project. The average glass wall is 3/8-inch to 3/4-inch thick. Single-pane glass can be up to 1-inch thick. Ask a professional about what type of glass is best for your project.
